Heavy rainfall can cause sewage backup due to overflowing sewers and clogged drains. This can lead to a messy and hazardous situation, especially if you have a basement or crawlspace.
Sewage backup during heavy rain is a common issue in many areas, and it’s essential to understand the reasons behind it to take preventive measures.
Why Does Sewage Back Up More During Heavy Rain?
Sewage backup during heavy rain is often caused by the combination of heavy rainfall and inadequate drainage systems.
When it rains heavily, the ground becomes saturated, and the water table rises, putting pressure on the sewer system. If the sewer system is not designed to handle the increased flow, it can lead to backups and overflows.
